The condenser fan is crucial for the proper operation of the
air conditioning system. The fan ensures a sufficient amount of airflow across
the condenser throughout the vehicle's operating range. Inspect the fan
during all air conditioning diagnosis procedures. Give particular attention
to the fan whenever excessive high-side pressure is encountered.
The condenser fan is designed to operate when any one of the following
conditions are met:
• | The A/C system is operating. |
• | The engine coolant temperature is 110°C (230°F) or higher. |
• | The PCM detects an engine coolant temperature (ECT) sensor malfunction. |
